Vanity After - Master Bath Miracle - Southernliving. This room’s layout remains unchanged to keep plumbing costs down. The new vanity proves the required plumbing parts don’t have to ruin the desired look. Open cubbies below the two bowl sinks have removable panels in the back to allow access to pipes. The new mirror above the vanity is cut to accommodate two sconces and faucets. A large cabinet to the right of the vanity adds storage.
